VEHICLE-AXLE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed December 8,1905. Serial No. 290.993.

To all whom, it may concern: I

Be it known that I, JAMES W. STANLEY, machinist, a resident of the city of Ottawa, in the county of Carleton, Province of Ontario, Canada, have invented certain new and useful Improvements in Vehicle-Axles, of which the following is a specification.

My invention relates to improvements in vehicle-axles; and the objects of my invention are to provide an axle of cheap .and simple construction in which the axle-spindle may be of the maximum strength possible and in which the wear thereon may be reduced to a minimum; and it consists, essentially, of an axle having a spindle formed thereon square in cross-section and tapered, a skein non-rotatably secured thereon and having the outer end screw-threaded and the inner end provided with an outwardly-extending annular flange, an axle-box rotatably mounted on said skein and held in position thereon by means of a cap-nut screwed on the end of said skein, the various parts of the device being constructed and arranged in detail, as hereinafter more particularly described.

Figure 1 is a side elevation of the righthand end of an axle with the box mounted thereon. Fig. 2 is a central longitudinal sectional view through the same. Fig. 3 is a sectional view on the line 2 2, Fig. 2.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the axle, having formed therewith a spindle a, which in accordance with my in vention is made of square or other prismoidal form and tapered from the juncture with the main axle to the end thereof, as shown. Nonrotatably mounted on this spindle is a skein B, the interior of which fits closely to the spindle, and the exterior thereof is conical to conform with the tapered end of the spindle. This skein is held in position on the end of the spindle by means of a pin a, which extends through holes provided in both the skein and spindle. The end I) of the skein is reduced in diameter and exteriorly screw- 7 threaded, as shown, and a cap-nut b is adapted to be screwed thereon. The interior end of the skein is provided with an outwardlyextending annular flange W.

C is the axle-box, which is rotatably mounted on the skein and also tapered to conform therewith, being held in position by means of the flange b and cap-nut b abutting against the ends thereof. When the parts are assembled, as shown in Figs. 1 and 2, it will be observed that the box will rotate on the skein, which will not move with regard to the spindle.

It is to be noted that tapering the end of the shaft to form the spindle in no wise reduces the strength thereo and this is a considerable advantage in the formation of my spindle, as in most forms previously used the axle is considerably weakened by reducing the diameter thereof at the point. Where the spindle joins it. It will also be noted that when through constant usage the upper side of the skein becomes worn it may be removed and replaced with the bottom uppermost, thus giving practically a new skein.

What I claim as my invention is- In a device of the class described the combination with a square axle of a tapered square spindle integral therewith and of exactly the same size as the axle at the point of juncture therewith of a skein having an interiorly square tapered recess fitting the spindle exactly and also having an exter nally-tapered cylindrical surface, a lockingpin extending through the skein and axlespindle, an outwardly-extending annular shoulder integral with the inner end of the skein, an axle-box inclosing the skein, and a cap-nut screwed on the end of the skein holding the box in position as and for the purpose specified.

Signed at the city of Ottawa, in the Province of Ontario, this 5th day of December, 1905.

JAMES W. STANLEY.
